See windows support..
Apparently new versions of Windows have something very like symlinks. (Or really, 3 or so things not entirely unlike symlinks and all different.) Stackoverflow has some details.
The windows port will not use symlinks. It will only support direct mode.
Lots of ifdefs and pain to deal with POSIX calls in the code base.
Or I could try to use Cygwin.
Deeper system integration
NTFS Reparse Points allow a program to define how the OS will interpret a file or directory in arbitrary ways. This requires writing a file system filter.
Someone wrote in to say:
For Windows Development you can easily qualify for Bizspark - http://www.microsoft.com/bizspark/
This will get you 100% free Windows OS licenses and Dev tools, plus a free Azure account for cloud testing. (You can also now deploy Linux VMs to Azure as well) No money required at all.
